Reliability and accuracy of artificial intelligence ChatGPT in providing information on ophthalmic diseases and management to patients

PURPOSE: To assess the accuracy of ophthalmic information provided by an artificial intelligence chatbot (ChatGPT). METHODS: Five diseases from 8 subspecialties of Ophthalmology were assessed by ChatGPT version 3.5. Three questions were asked for each disease: what is x?; how is x diagnosed?; how is x treated? Responses were graded by comparing them to the American Academy of Ophthalmology (AAO) patient guidelines, using a scale from −3 (unvalidated and potentially harmful) to 2 (correct and complete). MAIN OUTCOMES: Accuracy of responses on a scale from −3 to 2. RESULTS: Of 120 questions, 93 (77.5%) scored ≥1; 27 (22.5%) scored ≤−1; among these, 9 (7.5%) scored −3. The overall median score was 2 for “What is x?”, 1.5 for “How is x diagnosed?”, and 1 for “How is x treated?”, with no significant differences by Kruskal-Wallis testing. CONCLUSIONS: Despite positive scores, ChatGPT alone still provides incomplete, incorrect, and potentially harmful information about common ophthalmic conditions. ChatGPT may be valuable for patient education, but it is not sufficient without close human medical supervision.
